The present research examined the geographical distributions of Big Five personality traits in Japan. We conducted secondary analysis with three large datasets (survey 1: N = 4,469, survey 2: N = 5,619, survey 3: N = 4,330). We confirmed the spatial clustering of personality traits and mapped the geographical distribution in Japan. Moreover, we revealed the prefecture-level inequality of each Big Five domain across the three datasets. The results indicated that the metropolitan area and Okinawa showed higher Extraversion than Chugoku districts. Eastern Kyushu and Okinawa showed higher Agreeableness than Hokuriku districts. Tohoku district showed lower Conscientiousness than other districts. Tohoku and Chugoku districts showed higher Neuroticism than Okinawa. Northern Kyushu districts showed higher Openness than other districts. The results generally supported the hypothesis, and we discussed the regional characteristics obtained in the present study.
